Reduction method of zigzag type-2 uncertain variable and its application in two stage STP

The main purpose of the paper is to present the reduction process of type-2 zigzag uncertain variables with an application to a two stage solid transportation problem (STP). The problem under consideration has been described with all its parameters are in type-2 zigzag uncertain variables. To solve the problem, we have used the proposed reduction method which is based on expected value of the type-2 zigzag uncertain variables. Whole the research will describe the superiority to use the uncertain variables in transportation problem. In connection with the real life situation, we have encountered a numerical example with the help of practical data to show the use of our proposed reduction method in two-stage STP. All the soft computations regarding the numerical problem solution are performed in Lingo 13.0 iterative platform. At the last, the overall contribution, iteration and managerial facts have been outlined following the result.
